Therefore, in the embodiment shown, nethermost shedding motion 4a moves to the reception of anvil block 27 from chute 36 Inside element 29, the receiving element 29 of anvil block 27 clamps shedding motion 4a by vacuum action.

Herein, anvil block 27 is moved back parallel to direction X towards framework 26, to arrive again at resting position (Fig. 4), together When feed arrangement 40 reach apply position and to supersonic generator 81 and anvil block 27 feeding have open top 7 sleeve 6。

In the stage (Fig. 5), anvil block 27 is parallel to direction Y in the illustrated embodiment downwards in centre position movement.When When anvil block 27 is moved parallel to direction Y, anvil block 27 passes through the open top end 7 of sleeve 6 and reaches a position along direction Y, at this Position, receiving element 29 is aligned along direction X with the axis in hole 3.

Afterwards (Fig. 6), anvil block 27 is moved to parallel to direction Y and towards hole 3 (right side i.e. in figure 6) from centre position Operating position is moved, and supersonic generator 81 moves to operating position parallel to direction X from resting position.

When anvil block 27 and supersonic generator 81 are all in corresponding operating position (Fig. 6 to Fig. 8), shedding motion 4a connects Close hole 3 and be partially housed in the chamber 90 of supersonic generator 81.

More accurately, when anvil block 27 and supersonic generator 81 are all in corresponding operating position, the neck of shedding motion 4 Portion 9 and lid 10 enter chamber 90, and lid 10 cooperates with the wall 95 of ring 91, and flange 8 contacts the side 5a around hole 3 of packaging material 5, and And the side 5a (Fig. 9) of the packaging material 5 of the contact of sealing surfaces 89 packaging 2.

Additionally, lid 10 deforms the wall 92 of ring 91, to produce the axis B of the head 86 relative to supersonic generator 81 The part 93,94 (Fig. 9) being differently at an angle of.

By this way, ring 91 effectively makes the axis A of shedding motion 4 be centered in the axis B of head 86.

Finally, when the neck 9 and lid 10 of shedding motion 4 are accommodated in the chamber 90 of supersonic generator 81, in wall 92 Gap 100 (Fig. 7 and 8) is produced and lid 10 between.

In the stage, supersonic generator 81 is activated and head 86 vibrates, so that shedding motion 4 is sealed into sleeve On 6 packaging material 5 around hole 3.

Once sealing is completed, supersonic generator 81 and anvil block 27 return to corresponding resting position, and feedway 40 Return to resting position.

Subsequently, in a not shown manner, the top 7 (shedding motion 4a is applied with to it) of seal sleeve 6, so as to complete Into the formation of packaging 2.

In the stage, supersonic generator 81 returns to resting position along direction X, and anvil block 27 returns to centre position along direction X And resting position is returned to along direction Y, and circulation restarts again.

The advantage of device of the invention 1 will be apparent from description above.

Especially, ring 91 makes shedding motion 4a be centered in corresponding sonic generator 81 by made by elastomeric material It is efficient during 90 inside of chamber, and ultrasonic activation is not delivered into lid 10, therefore does not affect shedding motion 4a to be sealed to hole 3 On the packaging material 5 of surrounding.

Ring 91 is taper and has taper (taper) on the opposite side on opening 88 and surface 89.

By this way, the contact area between ring 91 and corresponding lid 10 is especially little.

Finally, due to the contact openings device 4a of surface 89 of the presence in gap 100, only supersonic generator 81.Therefore, by In the presence in gap 100, the mechanical oscillation of supersonic generator 81 is correctly delivered to the flange 8 of shedding motion 4a, and does not have There is the useless neck 7 and lid 10 that are delivered to shedding motion 4a.

Obviously, supersonic generator 81 can be changed, without deviating from protection model defined in the appended claims Enclose.
